DEVICE FOR JOINING INTERSECTING WIRES.

SPECIFICATION forming part of Letters Patent No. 472,059, dated April 5, 1892. Application filed August 6, 1891. Serial No, 401,923. (No model.)

To all whom t may concern:

Be it known that we, GEORGE M. LAMB and HIRAM R. LAMB, citizens of the United States, residing at Hillsdale, in the county of Hillsdale and State of Michigan, have invented a new and useful Wire-VVorking Machine, of which the following is a specification.

This invention relates to wire-working machines,-and has forits object the provision of a cheap and simple machine by which intersecting wires, as usually found in fences and similar structures formed of wire, may be rigidly and securely connected by means of wire fastenings, and furthermore to apply said fastenings with facility and dispatch.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to lthe drawings, Figure 1 is a perspective of a wire-working machine constructed in accordance with our invention. Fig. 2 is a detail in perspective of the anvil of the machine, the die being removed. Fig. 3 is a detail of the dies adapted to fit within the anvil. Fig. t is a detail in longitudinal section of the plunger-standard. Fig. 5 is a bottom plan of the plunger. Fig. 6 is a detail of the plunger. Fig. 7 is a detail in plan of two intersecting wire strands before fastening. Fig. 8 is a similar View after a single fastening has been applied. Fig. 9 is a similar View after a double fastening has been applied, the joint being reversely shown. Fig. 10 is a detail of the staple or fastening blank before bending. Fig. 1l is a detail of the fastener after bending, but before its application and ceiling. Fig. 12 is a detail of intersecting wires with the staple thereon, but before coiling.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates a cubical metal base or anvil, which is mounted upon a suitable support or table, and upon its upper face is provided with a central transverse dovetailed depression or recess 2 and at a right angle to the same with a shallow central semicircular groove 3.

4 designates a plunger-standard, which in cross-section is preferably triangular and has one of its faces, that crosses the point of intersection between the recess and groove 2 and 3, provided with a vertically-disposed or longitudinal shallow way or recess 5. To the face of the standard 4 and covering the recess, there is secured by screws or bolts 6 a faceplate 7, oblong in elevation and corresponding in size with the standard. Near its lower end the face-plate 7 is provided opposite the recess or way 5 of the standard with the oblong vertical opening 8, the inner lower end of which is beveled, as at 9. The standard et is provided with opposite lateral securing-plates lO, having perforations 1l, through which screws may be passed into a suitable support 25, loca-ted above the base oranvil 1, whereby the standard is supported a short distance above said base or anvil.

In the recess 5 of the standard there is mounted for reciprocation a plunger 12, slightly longer than the standard and above the same, having a head 13. Though if the machine is operated by power other than hand, the head may be omitted and suitable connections with the machine be substituted.

The bottom of the standard and face-plate at each side of the lower end of the recess 5 of the standard and at an oblique angle to the standard is provided with oppositely-disposed recesses 13L countersunk therein, and ateach outer side of the same shallow semicircular grooves 15 are formed the same, corresponding with the grooves 3 in the anvil.

16 designates a die, which in cross-section is dovetailed and removably inserted and f1tted' within the dovetailed recess 2 of the anvil. This die has formed in its upper face at each side of its center countersunk halfthreads 17, which constitute a die and register with the recesses 13a of the standard heretofore described. The die is also provided with a central longitudinal groove 1S and with opposite parallel transverse recesses 17 a, located at opposite sides of the half-threads 17.

19 designates two intersecting wire strands of a fence or other wire structure, which it is desired to secure together by the wire-fastener. (See Fig. 7.)

2O designates a short wire blank, (see Fig. 10,) which is bentinto U shape to form the sta- IOO ple 21. (See Fig. 1l.) The intersecting wires v are placed in the crossing grooves 3 and 18, and the staple is passed through the oblong opening in the face-plate and guided by the beveled edge of the opening into the recess 5 of the standard, and therefore into the path of the reciprocating plunger l2. The plunger, it will be seen, is diagonally disposed with relation to the intersecting wires, crossingthe same at their points of intersection, and is hollowed at its lower end to conform with the curved upper end of the staple or fastener. It now simply remains to depress the plunger, which in the present. instance is designed to be accomplished by hand, and such depression forces the staples down through the recess 5 and astride the point of intersection of the two wire strands. Both terminals of the staple take or are guided into the beginning of the threads of the die and at diagonally-opposite points in said die, and the points or terminals of the staple or fastener following the paths of the threads are coiled in opposite directions around one of the strands of wire, or, in other words, one terminal is coiled on a left-hand spiral and the other on a right-hand spiral. This constitutes a single fastening and is sutiicieut for some structures, it being apparent that when applieda secure connection is formed. If desired, however, the plunger may be withdrawn or retracted, (in this instance accomplished by hand,) the wire strands removed, reversed, and replaced and a second die l0, having threads oppositely-disposed with those of the iirst die 1G substituted for the iirst, and a staple or fastener applied to the strands and disposed ata right angle to the iirst staple and its terminais coiled in the same manner about the opposite or companion strand, whereby a double security and fastening is accomplished. The recesses 13 receive the upper portions of the coils as they are formed. The recesses 17 receive, during the operation of applying the second fastener and forming its coils, the coils of the fastener first formed and applied.

From the foregoing description, in connection with the accompanying drawings, it will be seen that we have provided a machine of cheap and simple construction adapted to apply secure and simple fastenings at the intersecting points of wire strands, whereby such structures as are now formed of wireas, for instance, fences, trellises, summerhouses, tc-are greatly strengthened and their durability increased.

Having described our invention, what we claim is l. The combination, with the base having a die located in its upper face and comprising portions of threads, of a plunger mounted for reciprocation above the said die and diagonally disposed thereto, substantially as specified.

2. The combination, with the base having a die located in its upper face and comprising portions of threads, of a standard located above the anvil and having a way or recess formed therein and communicating with the die between the threads thereof and diagonally disposed with relation to the threads, and a plunger mounted in the way, substantially as specified.

3. The combination, with the base having a die located in its upper face and comprising portions of threads, of a standard located above the anvil and said standard being provided with a vertical Way or recess communicating with the die between the threads and diagonally disposed with relation to the same, and an opening formed in the side of the standard and communicating with the way, and a plunger mounted in the way, substantially as specified.

4f. The combination, with the base or anvil having a die located in its upper face and comprisin g portions of threads and provided with intersecting wire -strand-receiving grooves crossing the die at its center, of the standard located above the anvil and in its under side provided. with a transverse groove agreeing with that of the lower die, and a plunger mounted for -reciprocation in the standard and communicating with the die between the threads thereof diagonally disposed with relation thereto, substantially as specified.

5. The combination, with theanvil having the dovetailed recess in its upper face and the transverse groove and the dovetailed die having port-ions of a thread formed therein located in the recess, of a standard having laterally-disposed securing-plates and triangular in cross-section and provided upon its outer face with a recess and a plate covering the recess of the face of thestandard and provided with an oblong opening, and a plunger mounted in the recess and provided with a curved lower end diagonally disposed to and located between the threads of the die, substantially as specified.

G. In a machine of the class described, the combination, with the base, the die, and the recessed standard located over the base, of a face-plate secured to the standard and over the recess and provided with an oblong opening,thelower inner edge of which is chamfered at opposite sides of its center, forming a guide, and a plunger mounted for reciprocation in the recess of the standard, substantially as specified.

7. The combination, with the base having a die located in -its upper face and comprising portions of threads and provided with intersecting wire-strand-receiving grooves, of a plunger mounted for reciprocation above the said die and between the threads and diagonally with relation to the intersecting grooves, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto aflixed our signatures in presence of two witnesses.
